SIPHON-HEAD.

SPECIFICATION forming' partof Letters Patent No. 711,461, dated October 21, 1902.

Application iiled October 24, 1901. Serial No. 79,833. (No model.)

To a/ZZ whom, it may concern.-

Be it known that I, CHARLES L. BAs'rIAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Siphon-Heads, of which the following is a specification.

This invention relates to novel improvements in heads for Siphon-bottles of the general character rst disclosed in my application Serial No. 69,510, led July 24, 1901, which are adapted for use in serving carbonated liquids in the ordinary way and also permit the carbonation of the liquid inthe bottle itself instead of inxa separate receptacle.

The object of the present invention is to avoid the accidental loss of gas and prevent the escape of any of the carbonated liquid withinthe bottle while the gas-supply is being turned on and off, and this is accomplished by opening the gas-inlet passage only while the gas-supply is turned on, and a further object of the invention is to utilize the pressure of the gas itself for opening the gasinlet passage to admit the gas to the bottle, and a still further object of the invention is to provide a valved gas-inlet passage entirely independent of the liquid outlet passage, whereby the liquid-outlet passage remains closed during the carbonating process and the gas-inletvpassage remains closed, except when the gas-supplyis turned on for conducting the carbonating process.

In the accompanying drawings I have illustrated a Siphon-head in which my novel invention is embodied, and referring thereto- Figure 1 is a sectional View illustrating the Siphon-head ready to have the gas-supply connected therewith. Fig. 2 is a similar View showing the Siphon-head in normal position and ready to be operated for serving the carbonated liquid in the bottle. Figs. 3 and 4 are sectionalviews similar to Figs. 1 and 2, except that the gas-passage terminates above the liquid-valve and the independent valve ink the gas-passage is dispensed with.

Referring to the drawings, in which like numerals of reference denote corresponding parts in all of the gures, lO designates the cap of the siphon-headcasing 11, which is inte- 4 riorly threadedv to engage an external thread 'chamber 16.

l2 on the neck of the bottle 13 or is otherwise adapted to be removably secured upon the bottle, so that the Siphon-head can be readily removed for the purpose of filling the bottle or cleaningthe same. The body 14 of the ycasing is bored toV form a chamber 15,

opening at its ,upper end and counterbored to form a chamber 16, opening at its lower end in the cap, these two chambers being connected to form a continuous opening throughout the length of the casing. A spout 17 is arranged on one side of the casing and provided with a discharge-passage 18, which communicates with the chamber 16.

A valve l9'is carried by the plug 20 on the end of the stem 21 and is normally held against its seat 22 at the bottom of the chamber 16 by means of a spring 23, which bears at one end against the head 24 of the stem and at the other end against a collar 25, which rests on a shoulder 26 in the casing above the The construction is such that the valve normally closes the liquid-discharge -through'the chamber 16 and the passage 18 of the Siphon-head, and when the Valve-stem is depressed to unseat the valve the carbonated liquid within the bottle may be served in a manner common to allsiphon-bottles.

The valve-stein is provided with a fluidpassage 27, which in the preferred coustruction of Figs. l `and 2 is shown extending throughout its length and opening at its top into a recess 2S in the head of thestem. The lower end of the stem is screwed into the plug 20, which is provided with a-valve-chamber 29 and a valve 30, carried by a stem 31 and normally held against its seat 32 by a spring IOO duced through the gas-passage in the stem of the liquid-valve without in any way affecting the liquid-valve, and after the carbonation is complete the liquid may be served by opening the liquid-valve Without in way affecting the gas-inlet valve. In the other construction (illustrated in Figs. 3 and 4) I em- 5 ploy only the liquid-valve 19 and dispense entirely with the independent gas-valve. In this construction the gas-passage 27 in the valve-stem opens through a lateral extension 27 into the chamber 16, and consequently the liquid-valve must be opened before the gas is admitted to the bottle. To prevent the escape of the gas through the discharge-spout when it is being introduced into the bottle for carbonating purposes, I provide a plug 36, which is screwed into the end of the discharge-spout to close the same during the carbonating process, and after the carbonation is complete the plug is removed from the spout and screwed into the recessed head of the valve-stem to close the gas-passage, so that carbonated liquid will not escape therethrough While being served in the ordinary manner and for a further purpose hereinafter described. In the preferred construction of Figs. 1 and 2 it is not necessary to plug the discharge-spout during the carbonating process, as the liquid-valve is not then opened, nor is it necessary to employ this plug for closing the gas-passage, because the gas-valve is not opened When the liquid is being served; but I prefer to use this plug to form a fulcrum for the lever 37, which is connected with ashoulder 3S on the casing by a link 39 and which is employed to depress the valvestem to open the liquid-valve.

In both the constructions illustrated in the drawings the gas-valve which permits the introduction of gas into the bottle is opened only When the gas is turned on and by the pressure of the gas itself. The head of the liquid-valve stem is located within the chamber 15 and below the top thereof, so that it will not be affected when the Siphon-bottle is arranged in the machine employed for agitating the liquid and promoting the carbonating process, such a machine being disclosed in my application, Serial No. 70,769, led August 3, 1901. It is desirable that the valve through which gas is admitted to the bottle should not be opened until the gas is turned on, so as to avoid loss of gas and pressure and also prevent the carbonated liquid from escaping from the bottle. By utilizing the pressure of the gas itself to open the gas-passage to the bottle the independent gas-valve in the construction of Figs. 1 and 2 and the combined gas and liquid valve in the construction ot' Figs. 3 and 1 are automatically opened by the outward pressure of the gas and closed by the pressure of the gas within the bottle, assisted by the springs. Vhen the supply of gas is turned off, the gaspassage is immediately closed, thereby preventing the contents of the bottle from accidentally escaping while the bottle is being removed from the carbonating-machine.

In the construction of Figs. 3 and 4 the combined liquid and gas valve may be opened to admit gas by other means than the pressure of the gas itself, if desired.

In practice the Siphon-head is removed and the bottle filled with Water, after which the Siphon-head is replaced and the bottle is arranged in a machine for agitating its contents while carbonio-acid gas is being admitted thereto. If the Siphon-head of Figs. 1 and 2 is used, the discharge-spout need not be plugged; but if the Siphon-head of Figs. 3 and 4 is used the discharge-spout must be plugged While the gas is being admitted to prevent the gas escaping through the discharge-passage, and this is accomplished by simply changing the plug 36 from its position, closing the gas-passage to the end of the discharge-spout. When the gas is turned on, the pressure thereof Will open the independent gas-valve of Figs. l and 2 or the combined gas and liquid valve of Figs. 3 and 4, and after the carbonation is complete and the gas turned o the valves of either construction Will automatically close, thus confining the carbonated liquid in the bottle. The plug 36 is then arranged inthe upper end of the liquid-valve stem, so that the valve can be opened for permitting the discharge of the carbonated liquid in the usual Way by applying pressure to the valve-stem through the medium of the lever 37 or other suitable means.

My improved Siphon-head is not restricted to use with bottles of any character or to use with any particular type of carbonating or charging machine, as it is apparent that gas could be admitted to the Siphon head or bottle and its contents agitated in machines of different kinds.

Having thus fully described the invention, What I claim, and desire to secure by Letters Patent, is
